THE SHOWERS AND THUNDERSTORMS THAT IMPACTED PORTIONS OF EASTERN

WILDFIRE SMOKE CONCENTRATIONS ACROSS MUCH OF THE AREA. WITH THAT
SAID, SOME SURFACE-BASE SMOKE IS EXPECTED TO LINGER OVER FAR

DISCUSSION
THROUGH NEXT MONDAY...
AS A TROUGH MOVES EAST AND EXITS THE REGION, SCATTERED SHOWERS
AND ISOLATED WEAK THUNDERSTORMS WILL CONTINUE THIS AFTERNOON FOR
LOCATIONS NORTH AND EAST OF BILLINGS. ADDITIONALLY, MUCH OF THE
SMOKE OVER THE REGION IS EXPECTED TO DECREASE AND MOVE SOUTH THIS
EVENING AND OVERNIGHT.
A FEW DAILY RECORD LOWS FOR AUGUST 4TH MAY BE APPROACHED EARLY
TUESDAY MORNING AS A 1020MB SURFACE HIGH SETTLES IN TONIGHT,
BRINGING MOSTLY CLEAR SKIES AND LOWS IN THE 40S TO LOWER 50S.
HIGHS TUESDAY WILL BE SLIGHTLY WARMER THAN TODAY, IN THE MID TO
UPPER 70S. THEN, A WEAK SHORTWAVE MOVING THROUGH WILL BRING A LOW
CHANCE (15-30%) FOR SHOWERS AND WEAK THUNDERSTORMS ALONG THE
MT/WY BORDER TUESDAY AFTERNOON INTO OVERNIGHT.
UPPER LEVEL RIDGING BUILDS IN FOR WEDNESDAY INTO THE END OF THE
WEEK, KEEPING CONDITIONS DRY AND ALLOWING HOT TEMPERATURES TO
RETURN. FRIDAY IS CURRENTLY EXPECTED TO BE THE WARMEST DAY, WITH
HIGHS NEAR 100. THEN, THE RIDGE FLATTENS SOME, WHICH WILL ALLOW
HIGHS TO DECREASE OVER THE WEEKEND TOWARDS NORMAL BY EARLY NEXT
WEEK (UPPER 80S TO LOW 90S). THIS MAY ALSO ALLOW ADDITIONAL
MOISTURE TO MOVE IN LATE SUNDAY/EARLY MONDAY, LEADING TO DAILY
AFTERNOON AND EVENING THUNDERSTORMS (20-50% CHANCE). ARCHER
